Alloy steel sheet
The steel plate is flat, rectangular and can be rolled directly or cut from a wide strip of steel.
According to the thickness of the steel plate, thin steel <4 mm (the thinest 0.2 mm), thick steel plate 4~60 mm, extra thick steel plate 60~115 mm.
Steel plate is divided into hot rolled and cold rolled according to rolling. The width of the sheet is 500~1500 mm; The width of the thickness is 600~3000 mm. The sheet is divided into ordinary steel, high quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet, etc. According to
professional use, there are oil drum plate, enamel plate, bulletproof plate, etc.; According to the surface coating, there are
galvanized sheet, tin sheet, lead sheet, plastic composite steel plate, etc.
